Answer:
False.
A codebook is not necessarily more essential for closed-ended questions and quantitative surveys. In closed-ended questions, respondents are provided with predefined response options to choose from, which can be easily coded and entered into a database without the need for a codebook.
However, a codebook becomes particularly important for qualitative or open-ended responses. It provides clear instructions or guidelines on how to code and categorize the free-response comments or qualitative data. It helps maintain consistency and standardization when coding and analyzing the qualitative data collected from such surveys.
